100 million year old dinosaur footprints

A trove of more than 85 well-preserved dinosaur footprints has been exposed near Hastings, U.K., thanks in part to erosion of the area’s coastal cliffs over the past 4 years, BBC reports. The prints are dated between 145 million and 100 million years ago, during the Lower Cretaceous period, and were made by several dissimilar species including herbivores from the iguanodontian family, an ankylosaur, a species of stegosaur, and theropods. The footprints were preserved in such “incredible detail” that impressions of skin, scales, and claws are easily distinguishable, the researchers report in Palaeogeography, Palaeoclimatology, Palaeoecology. The scientists say the collection’s diversity and detail will provide new insights into the creatures of the Cretaceous.
